all critical locations have huge DC batteries specifically design to take over during a short outage. Then generators.

There would always be a risk any backup systems fail. As another commenter pointed out, in other countries it would be illegal to cut power like that for that kind of reason. And that's a good thing. Power is literally keeping people alive and shouldn't be turned off because it seems mean to leave it on.

But a better point is, no one discussing this knows what downstream effects could happen if they killed the power. Seems kind of crazy to me to pretend we do.

A backup system that isn’t tested regularly is not a backup at all, just the illusion of one.

If you can’t turn the power off with 24h notice then nature will turn it off with zero notice at the most inconvenient moment.

They should indeed do regular tests of their backups. They should also ensure technical staff is on-site during those tests.

If their back up system fails then it’s their fault for not keeping it up to date. Seriously, my husband is an engineer who designs these battery systems. They do not “fail” if they are maintained and replaced properly.
